Ni ni was an amazing lecturer! She deserves better ratings here on bruinwalk. She makes the material super easy to understand, and is definitely engaging in lecture. Her lectures were really interesting and I genuinely walked out of each lecture having learnt something new, and actually understood it. She is super nice and always willing to help! Her midterm was very fair, very similar to what she said it would be like. The final was a lot harder, but still doable. Even if you don't do stellar, the curve will likely be in your favor, and you will get a good grade. Literally unless you get like a 0% on everything you will probably end up with at least a C in the class. She is also very concerned with students learning, and is always open to comments or suggestions and often sends out polls asking students about their opinions on the course and her teaching so far. She really cares and it shows! And by the way, her accent does not at all impair her teaching abilities, like others may suggest. Ni ni is one of the best physics professors I've had here at UCLA, I would definitely recommend taking phys17, or any physics class with her!

A lot of these reviews make Ni's class sound worse than it is. While she was a bit disorganized at times and would suddenly jump from introducing a concept to flying through derivations with terms seemingly coming out of nowhere, these were probably the worst parts of the class. Besides that, she really cares about her students and making sure that everyone understands the material. Throughout the quarter she setup countless demonstrations to show real-life examples of the concepts we were learning. In terms of homework, we would have one Mastering Physics assignment due per week which had enough problems to practice concepts without being too much work. Her first midterm was very easy with the average being in the high 80s. She ended up making her second midterm more difficult to counteract this, but it was still a fair test. The final was more similar to the second midterm in terms of difficulty, but gave plenty of time to finish everything. For those who still find the class difficult, Ni grades the class on a curve so while it may be hard to get an A, but thankfully it's almost impossible get below a C.

I really enjoyed taking this course with Professor Ni Ni. From my experience, she was extremely clear and explained concepts very well- more so than a majority of professors in the physics department could ever do. She is also extremely concerned with our learning and wants to make sure we get the material She must have improved on her teaching greatly because she really deserves a higher score here on bruinwalk.

Ni Ni was awesome, she gave engaging lectures and thorough explanations. Her exams were very fair and straightfoward.

The lecture was not clear at all. Prof was not good at answering questions. Not recommend.

Ni was a great professor and taught things very well. She is very nice and cares about all of her students. With it being an online class, she had some trouble setting things up but it still went fairly smoothly. The textbook was helpful for me, especially for the open book exams. She gave some extra credit by giving us quizzes that would add some points to our midterm and final exam grades.

Quick disclaimer, my lab section was basically run by my TA, so this review is more so regarding the class itself and my TA Maximilien Liese, rather than the professor herself (who I never saw). The entire class basically revolves around a bunch of small lab experiments that you work on in a group. You are assigned a group and are stuck with that group for every lab until the end of the class, unless you talk to the TA at the start to change groups (so make sure your group is responsible and splits work evenly!). We had prelab and postlab assignments, all of which were straightforward since clear instructions were given via google slides. The lectures were basically just background info and instructions being read off slides (so nothing special, but it gets the job done). The TAs and LAs are helpful and usually respond to emails quickly. No midterms, and the final is just a final project you choose and work on with your group, then present at the end. Overall, this class is quite a bit of work for 2 units, but it isn't super difficult and having a good group will make it manageable for sure.

Pros: Professor is nice, she follows the Griffiths book closely and tightly, so you feel secure about what you learnt. She has all materials pre-posted, notes (handwritten)/lecture videos. Plus the book, you know where to find answers for things.

Cons: She finishes all the content exactly the class before the final. You get homework during Thanksgiving and before finals week, on new content. Also, there's 4 in-class quizzes (one cancelled due to the strike) and a midterm. Overlapped with other classes, you get no week of break and constantly have to deal with it. Quizzes are fine though, they are just simplified HW problems, with integrals and formulas provided. It's just the class is constantly on you and stressing you.

You probably have to pick between her and Regan and I think it's 50/50. Regan throws lots of stuff at you without notes/context, but you'll be delighted. This is a normal book-following class, not as exciting, but you won't feel imposter syndrome and study at YRL until 6. Workload is 50/50.

Extremely boring course but an easy A. The workload is very manageable 99% of the time apart from the group reports which ramped up the amount of work during the weeks they were due. This course did not teach me much about physics nor coding. Would not take again.

Don't take her, enough said.
